NEW YORK (AP) — Negotiations resumed Sunday between striking Broadway stagehands and theater producers struggling to find a solution to their thorny, seemingly intractable labor dispute as theaters faced a third week of dark stages and mounting box-office losses.

Resumption of the talks — after a week of no negotiating — had been announced the day before by Charlotte St. Martin, executive director of the League of American Theatres and Producers, and were confirmed by the stagehands union.

"We are glad they accepted our invitation to negotiate," said Bruce Cohen, a spokesman for Local 1 of the International Alliance of Theatrical Stage Employees.

More than 2 dozen plays and musicals have been closed since Nov. 10, when the stagehands walked off the job.
